title: Residual renal function and erectile dysfunction in patients on hemodialysis.
abstract: BACKGROUND
  Residual renal function and erectile dysfunction are important parameters of quality of life in dialysis patients.
  
  
  OBJECTIVE
  The purpose of our investigation was to determine correlations between erectile dysfunction and residual diuresis in patients on hemodialysis.
  
  
  METHODS
  The survey was organized as a cross-sectional study in men aged up to 65 years on hemodialysis. All respondents voluntarily completed the questionnaire of the International Index of Erectile Function (IIEF)-5. Demographic and anthropometric characteristics, the duration of dialysis, smoking, alcohol consumption, residual renal function, comorbidity, and routine biochemical parameters were determined for all patients. The adequacy of dialysis was calculated as Kt/V. Based on residual renal function, the patients were divided into a group without residual diuresis and a group with preserved residual renal function.
  
  
  RESULTS
  Nearly two-thirds of our patients did not have preserved diuresis, while 82.8% of our respondents had erectile dysfunction. Patients with preserved residual renal function were heavier (P = 0.047) and had higher body mass index (P = 0.047), but the prevalence of cardiovascular disease (P < 0.0001) and erectile dysfunction (P < 0.0015) was lower, compared to patients without residual diuresis. The regression model also demonstrated a statistically significant relationship between the residual diuresis and the total IIEF score (b = 4.74; P < 0.001).
  
  
  CONCLUSIONS
  Hemodialysis patients with preserved diuresis retain erectile function better.
